Abstract: The crosshead has a body formed of solid, metal plate, and of substantially U-shape. It comprises a pair of spaced-apart parallel limbs which are bridged between by an integral transverse member, and the latter is bored through to receive a piston rod therein. Shoe plates are joined to the limbs to guide the body in reciprocation. In the combination with a connecting rod assembly and a piston rod, an end of the piston rod is directly fastened to the connecting rod assembly, and the crosshead is coupled to an intermediate portion of the piston rod.

Abstract: A bell crank type strip feeding apparatus is disclosed in which one arm of the bell crank is coupled to an actuator and the other arm has a feed pawl thereon for feeding the strip. The actuator is a crank pin which is moved along a circular path about a fixed center. The intermediate pivot of the bell crank is mounted for movement along an arcuate path in response to the circular motion of the crank pin. The intermediate pivotal axis of the bell crank is yieldingly supported so that it can move laterally of the arcuate axis path when the feed pawl engages a fixed stop. A shearing mechanism is also disclosed for shearing the strip material at the conclusion of the feeding stroke.

Abstract: An impact drive sprinkler is provided from a relatively small number of easily assembled components which can be formed predominantly from lightweight molded plastic or the like. The sprinkler includes a unitary sprinkler body having a lower riser tube rotatably supported within a one-piece bearing sleeve adapted for connection to a water supply riser or the like, wherein the lower riser tube is joined to an upper range tube through which an irrigation water stream is projected. An oscillatory impact drive arm and a spring are snap-fit mounted with a controlled spring preload onto the sprinkler body for spring-loaded rotation of the drive arm toward a position with a deflector spoon unit thereon interrupting the projected water stream.

Abstract: A crankdrive mechanism for the two piston Stirling engine which greatly reduces engine size and weight without increasing complexity or decreasing mechanical efficiency. A single throw crankshaft is located between the cylinders and within the reciprocation limits of at least one of the pistons. An inverted triangular yoke connects the single crankpin with the two connecting rods, which are in turn connected with the respective pistons. A rocking lever connects the yoke with the engine housing and absorbs any side loads associated with the crankdrive mechanism. Extensive clearance provided between the cylinders and in the pistons permits the engine parts to be arranged in a very compact manner with ample running clearance.

Abstract: A copying apparatus includes device for reciprocally driving an original scanning device having a drive source movable in a predetermined direction, a movement converting device for converting the movement of the drive source into a reciprocal movement in which the time required for backward movement is shorter than the time required for forward movement, output device connected to the movement converting device to put out a reciprocal movement for driving the scanning device, and speed control device for controlling the speed of the forward movement of the movable member so as not to exceed a predetermined speed.

Abstract: A drive mechanism for advancing workpieces through a plurality of spaced-apart work stations which are arranged so that the distances between certain adjacent work stations are greater than the distances between other adjacent work stations. During an advancing stroke, the drive mechanism moves each workpiece from one work station the entire distance to the next work station so that no workpiece occupies any space between adjacent work stations after the completion of the advancing stroke. The drive mechanism includes a rotary drive crank to which a plurality of drive links are pivotally mounted. Each drive link is connected to a transfer bar which is guidably supported for straight line reciprocal movement to engage and advance the workpieces. A predetermined half-cycle movement of the drive crank imparts contemporaneous movement to the transfer bars which are moved through different distances during the half cycle movement of the drive crank to advance all workpieces to the next work stations.

Abstract: A reciprocating indexing mechanism for linear and rotary outputs which has an output member which inherently reaches a zero velocity at each end of a stroke independent of the input velocity and which utilizes an angular input mechanism, commercially available, which has a rotative movement greater than 180.degree. but less than 360.degree.. The resulting mechanism has versatile kinematic characteristics during the stroke with a smaller acceleration discontinuity at the ends of the stroke than comparable harmonic mechanisms.

Abstract: Apparatus for automatically loading film transparencies into pre-closed slide mounts either of plastic or of cardboard material and having an internal pocket for receiving the film transparency which is inserted through an openable region near one edge of the mount. In loading operation, wedge means temporarily spread the openable portion of the slide mount, defining a passageway for the film transparency to pass through into the mount, and then the two sides of the mount are allowed to spring back to their closed position after loading. Advantageously, the film transparency is cut off from the filmstrip before loading, with the freshly cut end of the strip serving as pushing means for pushing the film transparency into its mount, and thus low inertial forces are involved, because the individual cut transparency has only a small mass to be accelerated and moved. The film strip is bowed into a longitudinally extending arch for providing longitudinal stiffness for pushing the transparency.

Abstract: In a forging machine where the frictional work is reduced in the driving system at the main crankshaft and its support bearings, especially at the moment a forging force is applied. A rotary driven crankshaft is connected to a crank mechanism, which has a connecting rod connected to the driven crankshaft. The opposite end of the connecting rod is pivotally connected to an arm for driving the main crankshaft in an oscillatory rocking motion, which reciprocates the hammer means.

Abstract: A continuously variable mechanical transmission comprised of a crankshaft or similar device driven by a suitable power source such as an internal combustion engine, which drives one or more pivotally mounted levers, pushrods and ratchet mechanisms. The levers drive pushrods which in turn drive the ratchet mechanism through a rack gear mounted on each pushrod. The output of the ratchet gear mechanism drives an output shaft and is varied by varying the position of the pushrod attachment to each pivotally mounted lever. Each pushrod is connected to a slot or guide on each lever so that the connecting point can be varied from close to the pivot point or pivot axis to the opposite end of the lever. By this means it can be continuously varied from low speed to higher speed by adjusting the connecting point of the pushrods to the pivoting levers.

Abstract: A balanced crankshaft mechanism for the two piston Stirling engine which permits the use of a single crankpin and eliminates side forces on the pistons. A triangular yoke has connected to its respective apexes the connecting rods for each piston and the crankpin. One end of a rocking lever is connected to said yoke at a point between the points at which the connecting rods are attached. The other end of said rocking lever is connected to the base of the machine. As the crankpin rotates, the separate connecting rods and their respective pistons are moved with a phase relation appropriate for a two piston Stirling engine, and side forces are absorbed by the rocking lever, rather than by the pistons. A simple means of balancing the reciprocating inertial forces is described, which is also applicable to other types of Stirling engines.

Abstract: A mechanism for dispensing individual napkins from a napkin stack comprising a sliding actuator, spring biased to extend out of a dispenser housing, connected through a connecting rod to articulate a pivotally mounted advancing bell crank. The normal disposition of the bell crank deploys a pin on the free end thereof adjacent and within a slot on the underside of the napkin stack, the articulating arc of the pin around the pivot being such as to engage the underside of an individual napkin. As the bell crank is thus articulated the napkin is advanced through a slot for use.

Abstract: A device for moving a curved plate bent in a substantially arcuate-shape along a curved path, in which a lift arm pivotably supported on a pivot is operatively connected at one end thereof to a lift arm bracket having a bent end portion in such a relationship that the extension line of the bent end portion of the lift arm bracket makes an acute angle with the axis of the pivot supporting the lift arm. Due to the fact that the lift arm is connected to the bent end portion of the lift arm bracket by means of a guide pin which is guided in a predetermined direction along a slot provided in the bent end portion of the lift arm bracket and the extension line of the bent end portion of the lift arm bracket makes the acute angle, namely an angle less than 90.degree.

Abstract: A device for moving a curved plate bent in a substantially arcuate-shape, in which a lift arm driven by a rotary shaft and carrying the curved plate at one end thereof to cause movement of the curved plate is pivotably supported on a pivot mounted on a base, and the axis of this pivot is directed to make an acute angle with the moving plane of the curved plate. In the device, the curved plate carrying end of the lift arm moves along a curved path the curvature of which is substantially equal to that of the curved plate, thereby preventing impartation of a stress tending to cause deformation of the device.

Abstract: Device for producing and adjusting the feeding stroke of a transfer feeder for use in a transfer press which has a carrier for mounting thereon a pair of parallelly spaced transfer bars extending in the longitudinal direction of a working table of the press. The carrier is reciprocally moved along a pair of guide rods extending parallel to the transfer bars by the action of a transmitting mechanism connected to a drive source of the press.

Abstract: An automatic integrated processor which sequentially develops, washes and, if desired, applies gum to the exposed surface of an offset photolithographic plate in appropriately separated processing stages. The exposed surface of the plate is subjected to a linear, reciprocating rubbing action by plural sponges, which rubbing action produces results surprisingly similar to those produced by a manual rotary action. A fully assembled processor of this invention requires only that it be connected to a water supply, a source of power, and to a reservoir for used, waste fluids. A single electric motor is adapted (a) to drive plural pairs of coupled drive rolls, (b) to reciprocate the sponges in frictional contact with a generally horizontal offset plate and (c) to agitate angularly disposed containers for developer and gum. The translation of the rotary motion of the electric motor to linear reciprocation in mutually orthogonal planes is effected by direct rod-actuated drives with swivel rod-ends.
